Finally fixed the turn signals, thanks to Bentley wiring diagram and
listees.  Here was the solution.

Traced wire from drivers side rear side marker to license plate
illumination, and found short.  Also found incredibly corroded connectors
and burnt bulbs on the license plate lights.  Used nitric acid solution to
clean them, and all works well.
